Explanation:
Detailed explanation-1: -Neuronal ion channels are gated pores whose opening and closing is usually regulated by factors such as voltage or ligands. They are often selectively permeable to ions such as sodium, potassium or calcium. Rapid signalling in neurons requires fast voltage sensitive mechanisms for closing and opening the pore.
Detailed explanation-2: -Nicotinic cholinergic, GABA-A, and the 5-hydroxytryptamine3 (5HT3) receptor are examples of ligand-gated ion channel sites.
